A week after he was caught in a manhunt that captivated the nation, Boston Marathon bombing suspect Dzhokhar Tsarnaev sat in a federal prison hospital in Ayer, confined to a small, single-person cell linked to the outside only by a narrow window and a slot for food.

The small boat in which he had hidden was removed Friday from a Watertown backyard by the federal investigators building a case against him.

And in ways big and small, Greater Boston seemed to be regaining its rhythm, with commerce in full swing on Boylston Street, where two shrapnel-filled bombs killed three people and injured more than 260 on April 15.

US marshals confirmed Friday morning that they had transferred Tsarnaev overnight to Federal Medical Center Devens, an all-male prison facility about 40 miles west of Boston that holds 1,044 inmates and pretrial defendants on the sprawling former Army base.

Now, Tsarnaev is one of seven pre­trial inmates in the Federal Bureau of Prisons hospital at Devens, consigned to a high-security section where he is receiving regular medical attention and scrutiny from guards, said prison spokesman John Colautti.

Other inmates there include 300 chronic-care prisoners, some of whom need mental-health services, and individuals in the federal prison system’s only residential treatment program for sex offenders. Twenty inmates are serving life sentences.

The boat where bombing suspect Dzhokhar Tsarnaev was found hiding last week was removed Friday from a yard on Franklin Street in Watertown by a team of federal investigators.

Tsarnaev’s transfer ended a wrenching week for bombing victims and staff at Beth Israel Deaconess, which offered counseling from social workers, psychiatrists, and clergy.

“People wanted to make sure we heard what they were feeling,’’ said Dr. Kevin Tabb, chief executive at the hospital.

Tabb said Tsarnaev was treated in a closed unit that had no other patients, as requested by law enforcement. The area did not allow contact with the 24 patients at the hospital who had been injured in the Patriots Day bombing, he said.

No staff members refused to treat Tsarnaev, and some administered care to both the suspect and those he allegedly injured. Although doctors and nurses treated Tsarnaev like any other patient, Tabb said, the work was emotionally difficult.

“They are both professionals and human beings. They are able to put it aside while they were in the room, but experienced a lot of conflict internally,’’ said Tabb, who during the 1990s worked in a Jerusalem hospital that cared for both terrorists and their victims.

Beth Israel Deaconess held a healing service attended by 200 to 300 employees Friday afternoon in a lobby. The hospital’s Inspirational Singers, an a cappella group, sang “Amazing Grace” and “America the Beautiful,” Tabb said. Employees cried and hugged.

Tabb said many staff members had logged long days since the bombing, including a trauma surgeon who arranged for psychiatrists and clergy to accompany doctors and nurses evaluating bombing victims.

One nurse worked in the Marathon medical tent and then in the hospital’s emergency room all night after the bombings.

The next morning, Tabb said, she was back on duty.

“She cried the whole way to work because she knew she had to be strong” once she arrived at the hospital, Tabb said.

Eight patients with bombing injuries remained there Friday. Other victims are being treated in other city hospitals.

As healing continued, state officials took stock of their response to the bombings and a manhunt in which Boston and several surrounding communities were locked down.

Governor Deval Patrick on Friday defended the decision to order residents in Boston and elsewhere into their homes during the hunt for Dzhokhar Tsarnaev, who fled on foot after being pursued and confronted by police in Watertown early on April 19.

Impromptu memorials to the Boston Marathon bombing victims drew crowds of visitors to Copley Square in downtown Boston at noontime on Friday.

His 26-year-old brother, Tamerlan, died after the shoot-out, during which MBTA Transit Police Officer Richard Donohue Jr. was wounded.

Authorities are investigating whether Donohue was hit by friendly fire. Before they fled to Watertown, the brothers are suspected of murdering an MIT police officer, Sean Collier.

“I think we did what we should have done and were supposed to do with the always imperfect information that you have at the time,” Patrick told reporters after a ceremony to recognize executive branch workers who had assisted the bombing response.

At the same news conference, State Police Colonel Timothy Alben rejected the suggestion that there had been a breakdown in data-sharing between federal and state anti­terrorism agencies. Alben said the State Police had sufficient access to FBI data. “I think we need to put this to rest. Last Thursday, when we went to the media and disclosed all of those photographs and videos, it was because we did not have an identification of who this subject was,” Alben said.

However, questions persist on Capitol Hill and elsewhere about why Tamerlan Tsarnaev had appeared on CIA and FBI watch lists, but did not receive greater scrutiny before or immediately after the bombings.

Meanwhile, the Associated Press reported that US intelligence agencies added the mother of the Boston bombing suspects to a government terrorism database 18 months before the bombings.

The AP, citing two officials briefed on the investigation, reported that the CIA asked for the Boston terror suspect and his mother to be added to a terrorist database in the fall of 2011, after the Russian government contacted the agency with concerns that both had become religious militants. About six months earlier, the FBI investigated Tamerlan Tsarnaev and his mother, Zubeidat Tsarnaeva, also at Russia’s request, one of the officials said. The FBI found no ties to terrorism.

The Globe reported Thursday that Russian authorities had warned the FBI about Tamerlan Tsarnaev and his mother. However, according to the official quoted by the Globe, Tsarnaev’s mother was not placed on US terror watchlist, as her son was, an indication that the FBI did not consider her a threat.

The Patrick administration said it is asking for federal relief for small businesses and private nonprofit organizations affected by the bombings.

The governor and legislators also have asked for a review of state benefits that the Tsarnaev family received. In a letter to Representative David Linsky, a Natick Democrat who chairs the House Post Audit and Oversight Committee, state officials said the parents of the brothers had received food stamps and Aid to Families with Dependent Children while Dzhokhar and Tamerlan lived with them in Cambridge.

Anzor and Zubeidat Tsarnaev, the parents of the brothers, received food stamps from October 2002 to November 2004, and from August 2009 to December 2011, according to the letter. Anzor Tsarnaev received cash assistance from Aid to Families with Dependent Children from January to March 2003, and again from August 2009 to June 2010, according to the state Department of Transitional Assistance.

Also, Tamerlan’s wife, Katherine Russell Tsarnaev, received food stamps and welfare benefits from September 2011 to November 2012, according to the letter. Tamerlan stayed at home to care for the couple’s young daughter, now 3, while his wife often worked seven days a week as a home health aide.

Linsky said Friday he was awaiting follow-up documentation from the department that would detail specific amounts of aid the family received. The governor and Linsky said they will examine the records to determine whether the Tsarnaevs were entitled to the benefits.

“We’ll do our own analysis of the documents. I will go where the evidence takes us,” Linsky said.

“My intent is to always protect the taxpayers. I want to make sure that those benefits were rightfully authorized and received.”
